It's an easy read, it's a lot motivating that I expect it to be. It gave me a good understanding on how and why some products became insanely popular by using methods outside the basic concepts of advertising.

I just finished reading this book and it's a well written book. His ideas are really insightful, I just wished he elaborated more detailed examples but other than that, Contagious is a really good book.
